This volume presents developments and practical implementations in the theoretical, numerical and applicable aspects of computer analysis, simulation, modelling, control and forecasting for environmental applications. The contributions come from managers, scientists and engineers attending the Eighth International Conference on this subject. Topics covered include: health and pollution; fluid dynamics; environmental management and decision analysis; chemistry, physics and biology; satellite data, image processing and remote sensing; renewable energies; databases; and software implementation.
